Trailblazer P0340 - Cam sensor test and replace
This is not a P0340 tutorial. This is what it took to convince me that the cam sensor in my 03 needed to be replaced. Doing the other tests that I did prior to this test would have made this video run way too long. The 5v and ground circuits were verified, it passed the tap test, cam count never dropped on the Tech2, so watching the cam sig was the next step. I have to admit I got lucky here. I only saw the glitch twice. With the problem being so intermittent I was expecting to have the drive the truck with the equipment hooked up to catch it. https://www.amazon.com/ACDelco-213-1557-Original-Equipment-Camshaft/dp/B000 C9GO8G/ref=as_sl_pc_tf_til?tag=may0ab3-20&linkCode=w00&linkId=6aab9f04f7b20 a1da407441123837c63&creativeASIN=B000C9GO8G Cam sensor bolt torque: 89 INCH/lbs. Update August 2013 - The first line of the description says that this is not a tutorial. Update October 2016 - I showed my three year old this video and even he understands that this is not a tutorial.
